AfterWindow Company in Claremont, CA
Westlight Windows & Doors is the window company Claremont homeowners call when the job has to be done right the first time. Claremont is not a one-size-fits-all market: the Craftsman bungalows near the Village need a different hand than the hillside tract homes backing up to the San Gabriels. We carry eight manufacturer lines, put every price in writing before work starts, and answer the phone with a live person around the clock. Call (903) 354-7134 for a free estimate.
Why Claremont Homes Are Different
Claremont splits into two distinct housing realities, and the work changes depending on which side of town you’re on. North Claremont’s foothill neighborhoods sit inside California’s Very High Fire Hazard Severity Zone. When permits get pulled for window or door work on streets abutting the Claremont Hills Wilderness Park, the city often requires the entire opening to be upgraded to a WUI-rated assembly: Class A fire-rated glazing, tempered dual-pane windows, and ember-resistant door seals. That’s a code trigger most window dealers in Pomona or Montclair aren’t routinely set up to specify or install.
Down near the Claremont Village and the Colleges, the stock is much older. Homes from the 1910s through the 1940s, many of them Craftsman bungalows and Spanish Colonial Revivals, still have original single-pane wood-sash windows and solid-wood entry doors with period hardware. Owners there want replacements that respect the house while meeting Title 24 energy rules. Add the Santa Ana winds that accelerate off the San Gabriel canyons, plus summer highs routinely above 100°F followed by sharp overnight drops, and window seals and frame joints in Claremont thermal-cycle faster than in coastal or mid-valley towns. The weatherstripping takes a beating, wood frames warp, and ember intrusion is a real concern during fire season.
Our Main Claremont Services
Most Claremont homeowners reach out to us for two things: swapping out failing windows before the next Santa Ana season, and replacing doors that no longer seal or lock properly. Each service has its own Claremont page with full details and pricing.
Window Replacement in Claremont
Replacing windows in Claremont means matching the product to the street. A hillside home in the fire zone needs impact-rated or WUI-compliant glazing, while a 1920s bungalow near the Colleges typically calls for a wood-sash look that clears the preservation bar and still meets Title 24. We walk every opening before quoting, and we write down what we find. See the full breakdown on our Window Replacement in Claremont page.
Window Installation in Claremont
New-construction and addition work in Claremont has its own set of rules. The city’s plan-check process on hillside lots often requires WUI-rated assemblies at every opening, and the thermal cycling from Claremont’s hot days and cold mountain-air nights means the flashing and sealing details matter as much as the glass. We install what the plans specify and stand behind the work in writing. Details are on our Window Installation in Claremont page.
Door Installation in Claremont
Entry doors in Claremont take abuse from sustained Santa Ana winds, and north-side homes in the fire hazard zone need ember-resistant seals and multi-point locking systems when permits are pulled. Older Claremont doors often have period hardware worth preserving, and we can build around that where the code allows. Our process and pricing for Claremont doors are on the Door Installation in Claremont page.

Pricing for Window Company in Claremont, CA
Every Claremont job gets a written price before any work starts. No door-step revisions, no surprises after the opening is cut. Here’s how typical Claremont projects line up:
| Service | Typical range in Claremont |
|---|---|
| Single-window replacement | $850-$1,400 installed |
| Full-home window replacement (8-12 windows) | $7,000-$16,000 installed |
| Window installation for new construction or additions | $900-$2,100 per opening |
| Entry door replacement | $1,500-$3,800 installed |
| Patio door replacement | $2,200-$5,500 installed |
| French door replacement | $3,000-$6,800 installed |
| Custom wood door replacement | $3,500-$8,500 installed |
| Fire-rated or WUI-compliant door assembly | $2,800-$7,000 installed |
What pushes a Claremont price toward the top of those ranges is usually the WUI requirement on hillside homes: fire-rated glazing, tempered dual-pane glass, and ember-resistant seals all cost more than standard assemblies. Historic-stock work near the Village can also add cost when period hardware or custom wood sashes are involved. The price we quote is the price you pay, in writing, because that’s how the Kingswell Guarantee works.

What Claremont Customers Say
"Got quotes from three companies. Westlight wasn't the cheapest but they were the only one who measured everything carefully and put it all in writing. Worth it. No surprises on install day."
- Craig Dillard"Our sliding patio door had come off its track years ago and we just lived with it. New one is smooth as butter. They hauled off the old one and vacuumed up before they left."
- Jessica Landry"Replaced eight drafty old windows that were basically single pane. The house is warmer already and the street noise is way down. Crew was on time both days and the price was exactly the quote."
- Harold Bemis
